Why use aluminum cans for soda cans?
Aluminum cans have the following advantages: not easy to break; light weight; opaque.
Wang Laoji and Babao porridge are relatively hard iron cans, because the packaged goods are not under pressure and are easily deformed with aluminum cans. The pressure inside the soda is greater than normal pressure, so there is no need to worry about deformation under the pressure. And the aluminum can can ensure the pressure of carbon dioxide in the soda, so that the soda can achieve a better taste effect.
